SPECIFICATION forming part of Letters Patent No. 599,449, dated February 22, 1898.

Application filed April l0, 1897. Serial No. 631,617. (No model.)

.To @ZZ whom t may concern.-

Be it known that I, CHARLES C. HUNTING-- TON, a citizen of the United States, residing at Memphis, in the county of Shelby, State of Tennessee, have invented certain new and useful `Improvements in Sheet-Iron Stoves, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention has relation to that class of stoves which are usually constructed of sheet metal and are intended for burning wood and other like fuel; and the invention has among other objects in view the provision of a cover constructed to remain cool enough to permit handling as the heat from the combustionchamber is impeded in its passage through the material of the cover.

Otherobjects and advantages of the invention will appear in the following description, and the novel features thereof will be particularly pointed out in the claims.

Referring to the drawings, Figure l is a central vertical longitudinal section of a stove embodying my invention. Eig. 2 is a horizontal section on the line 2 2, Fig. l. Fig. 3 is a plan, with a portion broken away, of the cover or closure of the fuel-supply opening.

Like letters refer to like parts in all the 1igures of the drawings.

A represents the sheet-metal body of the stove, having a suitable lining A', also of sheet metal, and flanged at its top, as at A2, forming an air-space between the body and the lining, whereby the body is not only strengthened, but is prevented from being warped by excessive heat.

B represents the top of the stove, having a collar B for` the uptake or pipe surrounding and seamed to the cover at the uptake-opening B2. The collar is provided with an inwardly-projecting flange which is covered by a fold B3 at the margin of the opening B2. This forms a cheap and serviceable manner of connecting the collar with the top The cover or closure C for the fuel-supply opening B4 of the top comprises three principal parts*to wit, a cone-shaped top C', provided with a suitable knob or handle C2 at the apex, and apertures C3, distributed in any desired manner, so as to permit the egress of hot air and the ingress of cool air. The lower edge of the cone is folded upon itself, as at O4, for the reception of the bottom C5 of the cover, which bottom is depressed and provided with a iiange C(i to be received by the fold C4 of the top in order to unite the two parts firmly together. The depression 'of the bottom forms a shoulder C7, which fits into the opening B4 of the top or into a collar B5, projecting upwardly therefrom around said opening. Within the depression of the bottom of the cover there is inserted a layer C8 of asbestos, which is secured within thedepression of the bottom by metal strips C9, laid upon the asbestos, and by rivets C10, passing through said strips and asbestos and the bottom, Fig. 3.

The cover constructed in the form thus described will remain cool enough to permit of handling the same without burning the hands, as the heat from the combustion-chamber of the stove is impeded in its passage through the material of the cover by the presence of the asbestos and of the ventilated airspace above the same.

There is no direct opening into the fire-box of the stove. The employment of a draftopening which gives direct communication with the fire-box is an ever-present cause of danger by reason of the exit of sparks and live coals from the burning fuel. To prevent the occurrence of accidents from this cause, I have dispensed with such directly-communicating openings in the body of the stove. l I therefore construct the body of my stove without any such opening.

To secure one of the advantages of my improvement-to wit, the supply of heated air instead of cold air to the combustion-chamber or iire-box of the stove-I construct upon the exterior of the body a iiue D, extending from near the bottom of the body to a point at or near its top and connecting with the interior by means of an opening A3, formed through the body at that point. Within the interior of the combustionechamber and secured to the body A, I apply in any suitable manner a wall or plate E, which extends from the top of the body and from a point above the opening A3 to a point near the bottom of the combustion-chamber. This forms the iiue or passage E, which communicates through the opening A3 in the body with the iiue D or passage D inclosed thereby. Now it will be seen IOO that the only air that can enter the stove must pass up the passage D through the opening A3 and down the passage E and enter the combustion-chamber near its bottom. By this construction not only is it impossible for any sparks to escape from the stove, but the air that enters is heated during its passage through the tlues, and is thus better prepared to produce perfect combustion of the fuel than if it were introduced at the temperature of the outside air. Now in order to control the re within the stove by a regulation of the entrance of the exterior atmosphere I provide a damper F, which may be placed at any convenient point Within the passages D and E and at any desired point in either passage; but for the purpose of maintaining within the outer passage D a column of heated air, even when the damper F is closed, I preferably arrange said damper opposite the opening A3 in the body of the stove.

There may be a double bottom to the stove in the fire-box thereof, and in this instance the secondary bottom Gis corrugated length wise and is removably fitted within the lining A. The corrugations of the bottom strengthen the same, thereby enabling it to better sustain the load or weight of fu'el within the stove as well as to prevent excessive heat at the iioor beneath the stove by reason of the airspaces existing between the corrugations and the bottom proper of the stove.

In regard to the damper or draft-regulator F any suitable form may be used; but in this case I have employed a Well-known register form provided with a handle F', projecting through the wall of the flue D, and in order that the position of the damper may be seenthat is say, whether it be open or closed, or partly in either condition-I may glaze the opening in the iiue D with mica D2 opposite the damper; but I do not restrict my invention to these particular details of construction, as it is evident that the material advantages thereof may be secured by changing such details. For example, the iiues D and E may be of sheet or cast metal, as desired, and in view of the greater heat within the stove than that without the flue E may be of cast metal, while the flue D may be either of sheet or cast metal.

What I claim isl. A cover for a stove comprising a bottom, an elevated apertured top and an interposed layer of asbestos or non-heat-conducting Inaterial; substantially as specified.

2. A cover having a recessed bottom provided with a peripheral flange, an elevated apertured cover having a peripheral fold and layer of asbestos within the recess of the bottom and confining-strips for the same firmly connecting with said bottom; substantially as specied.

In testimony whereof I affix my signature in presence of two witnesses.

CHARLES C. HUNTINGTON.
